Live in AL work in TN - error code AL40-050 ?

My Alabama state return was rejected with error code AL40-050: This return could not be processed for electronic filing by the state. Alabama Department of Revenue has returned the file with the following message: "Total Alabama Wages, Form 40 Pg. 1, line 5, must equal the total amount of all State Wages (including Wages Earned Out of State) as reported in Box 16 of the Federal 1040 W-2. Note: plus/minus +/- $3.00 variance allowance has been added to allow for rounding errors.

 

I'm wondering if the error has something to do with my situation -- I live in Alabama, but work out of Tennessee. I entered everything exactly as it appeared on my W2. My W2 has boxes 15-20 blank, so I left the corresponding boxes in TurboTax blank as well. Should I instead have entered my Tennessee wages there, as Alabama wages?
