Where do I input my Graduate Retention Program Eligibility Certificate?

If you are filing online, keep all your documents in case they ask to see them at a later date. If you are filing a paper return, include your 2017 Graduate Retention Program Eligibility Certificate, and the receipts that support your tuition amount.
