There is an error on the worksheet for calculating late payment penalties for the state of Minnesota (MN). The federal worksheet seemed to work without any problems (at least it didn't show that I owed a penalty). (FYI, I paid all my quarterly payments on time for both the federal and state returns. Also, the amounts paid were such that I should not have been assessed a penalty. I have small refunds on both returns and my estimated tax payments were equal for all 4 quarters for the state.)
The worksheet for MN assumes that the estimated tax payments made for Q1 and Q2, which were due 7/15/2020 for both the federal and state of MN, are applied as Q3 payments. This resulted in a small penalty on my tax return which not only was incorrect but prevented me from e-filing my state return. I decided not to file until I heard back from you. I was able to get around this problem by using 4/15/2020 and 6/15/2020 for the Q1 and Q2 payment dates respectively. Please let me know when this issue will be resolved. I do not know if this applies to other states as well.
Thanks in advance.
