I filed and it said I'll get back $1100. I filed an amended return and it said I will get 0. Which will I get? I added vehicle tax to the amended return.

Your amended return is processed separate from your original return.  You will receive your refund amount from your original return.

Your amended return assumes you already received your original refund (that is why the IRS suggests to wait until your original return has been fully processed before you amend), look on line 18 of your 1040-X form.  It should show the amount of refund that was on your original return. 

So what your were amending your return for, did not result in any additional refund due, or tax due.

It is most likely that the sales tax on the car made no difference to the return thus the zero on the 1040X ...

Look at the form 1040X …

Column A should have the figures from the original return, Column C the corrected figures and Column B the differences between the other 2 which needs an explanation on page 2 of the form 1040X.

If you completed it correctly you will see an entry on either line 16 OR 18:

On line 16 should be the amount you paid with your original return. If you paid nothing already then this line should be zero.

On line 18 should be the amount of your original refund you received.  If you have not received your refund yet then you need to wait for it.  If the refund changes from what you expected then this line must reflect that change.

Then you will see your extra refund on line 22 OR  the new balance due you need to pay on line 20.
