It was not clear to me you were testing the upper AGI limits, and that was what you were talking about (I see you did mention it later, bit I thought the 100% you mentioned was referring distinguishing between that , and to lower limits for certain types of donations to 20% or 30% organizations).....I certainly didn't test the usual "60%" AGI limit for cash to 50% charities....just that I could enter cash donations at will in the interview..
OF course there is a limit to to 2020 donations, it just happens to be 100% of AGI for 2020 taxes. So yes...for that part you may have to wait until later this month for it to be implemented...might even take software folks until Feb if they get hammered trying to implement al the other stuff Congress/President just enacted ridiculously late in the year.
