The Federal MFJ vs MFS Comparison worksheet is not calculating "Less: credits", correctly.

It is reporting the same amount for TAX and Less: credits which results in a TOTAL TAX of zero and a refund amount equal to the total tax withheld.

You have to override and enter the correct "Less: credit" amount in order to get an accurate refund amount for comparison.

The State of Ohio MFJ vs MFS worksheet is calculating correctly for comparison.
