Did you file Joint for 2024 (and include his info & income)? If your 2025 joint return rejects and you want to file Married filing Separate then you will need to start a new account and not transfer from 2024. You can’t remove a spouse.
FYI - there are several credits you can't take when filing separately, like the
EITC Earned Income Tax Credit
Child Care Credit
Educational Deductions and Credits
And contributions to IRA and ROTH IRA are limited when you file MFS.
Also if you file Married Filing Separately up to 85`% of your Social Security becomes taxable right away even with zero other income.
