I have a pretty straightforward return, take standard deduction etc. I took an RMD from beneficiary IRA's in December as well as making a Roth conversion at the same time and paid the estimated taxes well before the 4th quarter due date. TT says I am receiving a refund of approximately $3000 yet am being assessed an underpayment penalty. This is the second time I am paying estimated taxes, with basically the same scenario and did not get this penalty the last time with fairly equivalent numbers so I don't really understand why.
Also, what is the benefit of waiting for Form 2210 if that says it is for fisherman and farmers, of which I am neither.
Thanks for any explanation, advice.
