What finally worked for me is going to Federal > Click on Other Tax Situations > Under Additional Tax Payments > Underpayment Penalties Then changed the owed amount in 2017 to 0. Then deleted the 2210 form, and IGNORED the warning that popped up that my returns had been rejected and submitted them anyway. Shortly got a message saying the return had been accepted. I pay way too much to TT to be spending three or four hours figuring out a workaround for this problem.
