Get your taxes done using TurboTax

2/17/2019  IRS rejected due to form 2210  IIa box (saying 85% waiver) checked with no supporting documentation.  Unable to uncheck box, find a supporting page 2 form to provide information IRS is seeking, or delete the form entirely (letting IRS figuring penalty if any).  Also, see that some updates were provided, but unable to locate any updates (I utilize the on-line TT product).  Ive closed TT, restarted my router and computer, accessed T to no avail.  Very frustrated over quality of TT this year...
