Alabama error code AL40-050

My husband withdrew from his 401K- Alabama keeps rejecting our return with the AL 40-050 error on our 1099-R Form.  I am guessing that because the payer of the 401K is located in Iowa, Alabama is flagging us as recieving money from working in another state? 

 

We didn't work or recieve money from another State, just the 401k which was through his employer in Alabama is based out of Iowa. 

 

I don't know what to do to remedy this issue.
