Form 2210 populated for my client and when I checked mark box C the red error disappeared from left pane. Client has $45 penalty on page 2 of 1040 as well before checked mark of box C,  after it was marked $45 penalty disappeared on page 2 of 1040 and the penalty deducted from the refund amount.

If I don not chechmark box C, the $45 penalty back to page 2 on 1040.

Also the top of the form 2210 says not ready to EF till 03/17/2022!!! I was wondering the reason form 2210 was populated is because of underpayment estimated tax or.... and the way I did it is right? I called many times ProSeries Support team no one answered!!!!!!!!!
