After you file

You are not clear on what "documents" you want.  You can print out your tax returns for the lender.  If the lender wants copies of documents showing income such as your W-2's or any 1099's, TurboTax does not have those.

I NEED A COPY OF MY W-2  (or 1099)

TurboTax does not have a copy of your W-2—the Wage & Tax Statement—issued to you by your employer, (nor does TurboTax have copies of your 1099’s).   You should always save those documents for your own records. You could ask the employer(s) for copies or you can get a copy from Social Security (for a fee of $86).

If you saved a pdf of your completed tax return, the worksheets will show the W-2 information you entered, but not the actual W-2.

You can get a wage and income transcript from the IRS:  It will not show the actual W-2, 1099’s, etc, but will show the income information the IRS received.  It will not, however, show your state information. It will only show the federal information.

Or you can pay the IRS $50 for an actual copy of your tax return which will include copies of your W-2’s

There are about two dozen kinds of 1099's.  A 1099Misc is typically issued by an individual or business for whom you performed work as an independent contractor, so seek a copy from them if you did not save yours.  Many of the other types of 1099's are issued by banks, brokerages and other financial institutions from which you can seek copies.
