I have a value in Box 4 on form SSA 1099 for benefits repaid to SSA. I see no where to enter it in the program. Does it need to be entered?

No. the amount from box 4 of the SSA-1099 is not entered on a tax return.  Only the amount from box 5 is entered on the return.  The box 5 amount is the result of box 3 minus box 4.
