After you file

If you owed on the original return but will not on the amended return then don't worry ... when the amended return finally gets processed it will balance out AS LONG AS  you filled in the amended return correctly.   The amended return ASSUMES you paid the original balance due on line 16 ... so look at your 1040X ... does line 16 reflect the amount you actually paid ???     If not then you need to recompute lines 16 - 22.
