I have the same issue with the Maryland 502UP. The form auto populates Line 11 4th Period with the same value as Line 1. This is an error according to the instructions for the form, "Enter in each column the income received for the period of the year covered by that column." The form should allow me to enter my values the same as it does for 1st, 2nd, and 3rd Period columns. I understand the point that the number entered on Form 502UP Line 1 is computed on the Maryland Resident Form 502 Line 16, and includes "Subtractions from Maryland Income", but there is nothing in the 502UP instructions which says the two values must be the same. The instructions only state that 4th Period income must be, "...100% of your income...".
When will this problem be resolved to allow me to enter my own values on Form 502UP Line 11 4th Period?!
