You can actually read about the placement and aspect anywhere on internet but I'll write brief description without former experience.
I think the thing with having chiron in Taurus is about feeling secure in your 3d world. You may not feel secure, with your place in the world, feel that you have no safe haven to be in. Also it is about a possessions, you may not know how to possess things, be to possesive or not at all, the idea is that you have to learn how to deal with possesions and figure your own way of ture balance in possesing things and valuing what you possess. Another ting maybe about materializations and materialism, you may value things merely materialistically or you may have a hard materializing your own world around you. These are the issues you need to deal with and learn about, and then you'll become good at this and have the ability to have a system about this issue.
Sun square chiron: THese issues above are one the main thing you'll have to deal with to be in your full life. You'll see that you are encountering these issues on a daily basis, and feel that you need to deal with them for your personal fullfilment. You have the power to overcome this by your own reasources and will have to work your way out, then this will eb a storng point in your life.
Chiron opposite Uranus: Your way of expressing yourself individually and eccentrically is hampered by the ssues above. You may find that you become so fiery and explosive when dealing with these issues, or you are making them grow over your head. You need to be preacautious to a tendency to make too big a deal or taking them off of your sight totally, or thinking you are already doing too well before you do. You need adopt balance whn dealing with this, but it is also that you'll need to work these issues out to express yourself individualistically in your full expression. You may have help from others in dealing with these reconciliation, or you may take others as examplars or mentors.
Chiron sextile midheaven: Dealing with the issues above is one of the main things you'll deal with in your life, you'll see that it continually comes in your presence, whenever your want to be present in a career sense, and also and more importantly as the role you're taking in your social public life. Working this out will be a strong point of you that you'll be able to take pride in.
Chiron quincunx ascendant: You may find that, dealing with the issues above does not come handy to you, that you cannot really hold them on you, it does not come natural. You may feel that you are not to deal with these energies. But looking at the other aspects, know that you'll have to. As you have not written what signs are these placements in I'm writing a very general outline. The thing with the quincux is that you'll first need to recongize and differnatiate the effect of he planets involved and the integrate them as harmoniously as possible.
Also looking at the sun and midhaven and also ascendant aspects, though there is disharmony in ascendant, you may find yourself in a position to use these healing ability (the ability to first learn and teach how to deal with possessions, learn how to possess materialize and form a secure haven) professionally.
