I have a capital loss carryover that turbotax automatically applied (but not the full $3,000 max amount but it did not seem to increase my refund.

A capital loss carryover would normally affect a difference in your refund or balance due, however it all depends on the overall income level when including your other income.  If your income is already below the filing requirement, then it would seem like it had no affect.

 

You can review your tax return (Form 1040 and Schedules 1,2,3) before you finish your return and you can also print the entire return before you file after you pay. Keep in mind that you will also have carryforward in some cases when the loss cannot be used up.

• Print a copy of my TurboTax Online return

You can view your 1040 form before you e-file:

1. Open or continue your return. (TurboTax Online)
2. With the Tax Tools menu open, you can then:
   • View only your 1040 form: Select Tools. Next, select View Tax Summary in the pop-up, then Preview my 1040 in the left menu.
