myactuary's method to delete Form 2210 (Window version) works to me. The IRS accepted. The only thing is the TurboTax added 13 dollars penalty.

Turbo Tax didn't do anything to fix it. It says no worry, we'll help you walk through to making update, but nothing happen, you can't find anything helpful. Wha...

Same Issue! Very disappointed with TurboTax! Very stupid software! Waste lots of time then you get rejected again!
