After completing SD-100 school district taxes, they are saying I need to mail a check as though I didn't pay into school district, when I overpaid and TT doesnt see it

I always overpay by about $100 into school district. Did the same this year, owe them 517, paid 613, yet turbotax says I need to mail a check for the 517, and I can't find any way to alter the forms or change anything

Go back to the W-2 screen, in the federal section of TT.  Be sure OH in in box 15. On that same line, the SD withholding ($613) should be in box 19 and the SD number in box 20.  Box 20 should be in the format  #### or SD#### (e.g. 1234 or SD1234). Box 18 is the amount of income subject to SD tax (usually, but not always, the same as box 16).  

If the W-2 is correct, that info should transfer automatically to the SD100.
