In box 14 I have a description of PA-LO1R but I don't know what I should put for the category.

Choose other not classified it’s at the very end of drop down menu

It most likely refers to Local Services Tax, which is an employment-related tax that isn’t based on your actual income amount.  

It’s not a deductible local income tax, so enter it as Other (not classified).

See the pdf W-2 Frequently Asked Questions for more information.  Since it’s sometimes hard to load from pdf links, here’s the actual URL:  https://www.budget.pa.gov/Services/ForAgencies/Payroll/Documents/w2-faqs.pdf.

Thank you!
