Q. Where do I add her info from last year?
A. You don't enter her info, from last year. Basically, in a "got married in 2023" situation, you can only transfer the data for one spouse from past year TurboTax or other tax software.
You enter all her this year info, manually. Once you enter her personal info, it may be possible to import some documents, e.g. W-2 or 1099. TurboTax will give you prompts for imports.
