From various posts, the software users appear to have found a workaround by manually editing the form. On-line users who started their return after 8915f was officially available do not seem to have the issue. I believe I found a way to solve the issue for users that already started/finished their return but were waiting on 8915f, and do not want to start over. Go to tax tools and delete the forms associated with the Qualified Disaster Withdrawals. You will then need to re-enter that you took the 2020 withdrawal and enter the amounts (deleting eliminates the information that TurboTax carries over from prior returns). I cannot confirm yet that the IRS accepted the e-file, but when I reviewed the finished 8915f form, it was properly filled out; nothing in C and box in D checked.
