Should Check This Entry, Sch 1, Line 5 description be preventing me from completing GA state taxes? What should be entered here? And where do I fine the information?

Line 5 on the GA Schedule 1, is for "Other Additions" to GA income.  In the GA state interview, "Edit/Update" the "Income" and scroll to the bottom of the topic list to find the "Other Additions" topic.  There you will be able to add a description for any income items listed there or delete/backspace in the boxes to get rid of any stray characters that may be incorrectly showing as an income entry.
