I replicated the 2021 returns for the married filed separately. Now I'm getting ready to start the 2022 returns, however this year it will be file "Married Filing Jointly". Can this be combined at the outstart to bring in prior year's information?
Nope. There are some options available (take the more complex return and add the less complex return to it, do an "as if" 2022 joint return and proforma that), but you're going to have to make a bunch of manual adjustments regardless.
