I'm single, made $35,000 yearly and only took home $800 total fed and state. Something seems wrong! But I already filed. Box 12 is blank on my W2 yet $2,300 was on PDF

You might want to check your return to see what happened.  You can check in TurboTax by following these steps:

1. On the right hand side of your screen, select Tax Tools,
2. Select Tools,
3. Select View Tax Summary,
4. On the right hand side of your screen you will see Preview my 1040.

Look over your return.  If you made an error in filing your return,  you can file an amended return.  

If the IRS accepts your original return, then you have to wait until it has been fully processed and you have received your refund.  Then you can prepare an amended tax return 1040X and mail it in.  You cannot e-file an amended return.

Do not change anything on your return until you start the amended return in TurboTax.
