Do you have a code a W-2 box 12 amount and code that indicated a retirement plan contribution? It might be applying the Savers Credit that required an additional schedule not supported in the Free version.
Two options if that is what it is for:
1) You might be able to use the Free File Edition for incomes under $36,000 and supports all states and most forms.
And get the credit.
The Free File Edition is part of the IRS Free File alliance and is totally separate from TurboTax website. The IRS Free File should not be confused with the TurboTax Free Edition that only supports simple tax returns.

2) In the "savers credit" interview answer "yes" you are a student. The answer does not go on the tax return or affect anything else, it simply "fools" TurboTax to remove the credit.
