Pennsylvania does not allow electronic filing of tax returns that have a 1099-MISC or 1099-G which report PA withholdings. If you have mistakenly reported PA withholding on either a 1099-MISC or 1099-G (unemployment), correct your data entry and the alert will clear. If the data is reported correctly and you had PA withholding on either form, you will have to paper file the return and submit the 1099 form to document the withholding.
