I filed a 740NP instead of a 740NP-R for Kentucky. What do I do yo fix that?

Wait until you get your refund or you hear from the KY Dept. of Revenue.  if the refund isn't the right amount, then file an amended return. 

 You should get a full refund of KY state tax. None of the local tax (box 19 of your W-2) is refundable. 

The reciprocity agreement does not apply to local city taxes.  You can not get those refunded, but if you live in an Ohio city with a tax, they may give you a credit or partial credit. Many do.  You need to check with your city.

If you are subject to Ohio School District Income Tax (SDIT), you can not get a credit, for KY local taxes withheld, on an SDIT return.
