How to file using Carnival Cruise w2 for state wages(boxes 15-17), receiving error code AL40-050

Alabama Code AL40-050 is a rejection on your return because your total Alabama Wages 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. 

If you live in Alabama, all of your income (no matter where it is earned), gets reported on your resident return.

The first thing you want to do is make sure you've filled out the Personal Info section correctly:

1. With your return open, select My Info in the left-hand menu.
2. Then, on the Personal info summary screen, scroll down to Other State Income, and select Edit.
3. At the Did you make money in any other states? question, answer Yes and make sure your nonresident state is selected from the drop-down.
4. Select Continue to return to your Personal info summary.

Now, what does your W-2 state? Is there anything in Boxes 15-17?

If not, then choose the state in which the wages were earned (even if there was no state tax withheld) in the dropdown box (Box 15) and enter their federal payer ID (as shown in Box b). Then, add your wages in Box 16. This will fix your error and you will be able to refile your return.
