Did you mean you have an ITIN?

For a PTIN see: https://www.irs.gov/tax-professionals/ptin-requirements-for-tax-return-preparers

A PTIN is for a professional tax preparer such as a CPA. Do you mean you have an ITIN? (Individual Taxpayer Identification Number)

Are you a resident alien in the US? Or a non-resident alien?

Do you have a green card?
