My first question is, why are you amending your return if your “partner“ received a corrected W-2? You can’t file a joint return with your partner unless you are legally married (including same sex marriages). If you are not married, your partner’s return should not change your return.
Then, whether you are using TurboTax online or TurboTax installed on your own computer, you can save the amended return as a PDF file, and then open the PDF file and selectively print the pages you need. The forms that are actually part of your tax return will have an OMB control number and an “attachment sequence“ number in the top right corner. Other documents are probably TurboTax instructions and TurboTax’s internal worksheets.
