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...
Try this - Click on Federal > Click on Other Tax Situations > Under Additional Tax Payments choose Underpayment Penalties - Answer the on-screen questions, except set the amount owed in 2017 to 0, leave the rest at the default settings that TT imported and Form 2210 will be left off your e-file. After you've answered the questions, you can confirm Form 2210 has been removed by going to Tax Tools > Tools > Delete a Form. It will then show you a giant list of all of the forms in your return. 2210 should not be in it.
In the desktop version in the instance where I needed to "uncheck" Part II, Box A, the method that worked for me was to override the check box and then you can uncheck it.
Well...in hat case, you may have to wait until TTX issues their next "fix" for it.
I don't know why you cannot do the override like everyone else can.....not that the override would end up working to allow you to file anyhow...I don't know what the final word is on that yet...
