Actually I had entered the estimated taxes for each quarter but reviewing the info I discovered they had the incorrect dates of 7/15, 7/15, 9/15 and 01/15 instead of 4/15, 6/15, 9/15 and 01/15 for both Fed and State. Once corrected the underpayment penalty went away. I am assuming TT used those dates by default as the IRS changed the due dates estimated taxes. So I am wondering if a person had actually waited for those dates to pay their estimated taxes they are subject to a potential underestimated tax penalty or if its a bug in TT. Anyway its now fixed. Thanks.
