Re how to report a bug, I spoke with an agent last night about this. Couldn't get the agent to tell me a way to report a software issue. The agent suggested paying the extra fee to get a tax rep to help.
Soccerdavid's screenshot clearly shows one of the problems. The entry in line 10, col (a) is the sum of columns (a) and (b) from SchedAI, line27. Again this is TY2020 logic so it looks like that was never updated for the redesigned TY2021 form. There are numerous other issues with this form.
Hopefully, Intuit will get this fixed soon (how about with Form 2210F release, if they're listening).
