What 1099? There are over a dozen kinds of 1099's. What kind of 1099 are you trying to print? Who issued it to you? TurboTax does not have copies of your 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.
