Check to see if Line 7, Federal Adjusted Gross Income, of Form IT-540 reflects the adjusted gross income (AGI) from your federal return. An unusual computation may be going on.
According to the instructions for Line 7 of your Louisiana return in Instructions for Form (IT-540):
If you have any exempt income or deductions other than what is reported on Line 8C or Line 9, you need to complete Schedule E to determine your Louisiana Adjusted Gross Income. In order to complete Schedule E, you may need to first compute your modified federal income tax deduction on Schedule H if you claimed federal disaster relief credits on your 2021 federal return. Mark an “X” in the box on Line 7 if the amount from Schedule E, Line 5C, is used.
[Bolding mine.]
Schedule E, which you can see with Form IT-540 included in the first link above, should take the disaster computation into account when computing Line 7.
