Hi Yilun Sun,
Welcome to Microsoft Q&A Forum, thank you for posting your query here!
To correct the typo in the return value for the “Married filing separately (MFS)” option on the 1040 form, you need to locate the section of your code where the filing status is defined, change married_filling_separately to married_filing_separately, and then test the change to ensure it doesn’t affect other parts of your application. Once verified, you can deploy the updated code to your production environment. This ensures the correct return value is used consistently.
Kindly refer the below document for any guidance.
Hope this helps. Do let us know if you any further queries.
