What is "Schedule 3, Nonrefundable Credits"? TurboTax says that I have to upgrade. Is there anyway to know exactly what on my return caused this?

[Rachel_W]

Schedule 3 is a new form this year that may be needed along with your Form 1040.  It is used to report "non-refundable credits" such as the:

• Foreign Tax Credit
• Credit for Child and Dependent Care Expenses
• Education credits
• Retirement Savings Contributions Credit
• Residential Energy Credit

 You can click this IRS link to view Schedule 3: https://www.irs.gov/pub/irs-pdf/f1040s3.pdf.

We are not able to see your return on this forum, but my best guess is that the credit requiring you to file Schedule 3 is the Retirement Savings Contributions Credit.  Please click the link to this TurboTax FAQ for more information: What is the Savers Credit?
