TurboTax does not have a copy of the W-2 or Form 1099.
It would have a Form W-2 Wage and Tax Statement that included the tax data from the forms that were entered.
The forms would be included in the PDF of the tax return in the tax year the return was completed.
Copies of a Form 1099 would have to obtained from the issuer of the form.

You do not say what kind of 1099 information you entered or that you are looking for. There are over a dozen kinds of 1099's. A 1099NEC 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.
