Retirement tax questions

when I called the number mentioned in turbotax, PA help resources told me consider this retirement plan distribution and hence taxable if under 59 years. I told them that I paid premium every year for 7 years and this plan matured 20 years later and took retirement distribution

The difference in distribution and cost is taxable. Do you know where I need to enter this Other reportable income from federal into PA state?
