State taxes withheld for wrong state

I live in Ohio.  Pa Employer. Employer shows PA income and Pa state taxes paid for part of the year.  Also Ohio  income and Oh taxes for remainder of year. 

1. How do I get my money back from PA?   File non resident income tax and change the income to $0. have to pay $40 for another state in Turbo tax.

2. Ohio is showing I underpaid and charging $37 penalty.  Anyway to avoid paying the penalty?
