kbernstein had a solution earlier. I tried and it worked. Repost the solution below:
FINALLY -- I successfully filed my return! Here is how:
Go to Forms View
Go to Part II: Reasons for file
Right Click near Box with X in it to get short menu and press Override (may need to move mouse around to get correct spot to do this)
Remove X in Box
This makes the Form 2210 not needed, but leaving in it evidently caused no problem.
(I tried to do the same for the words "85% waiver", but they are still there and did not matter.)
Save and file your return. Received an acceptance in less than an hour.
Note I am using Desktop TurboTax on Windows 10.
