You do not get a 1099R for Social Security. You get SSA1099.
If you saved a pdf of your completed tax return, the worksheets will show the SSA1099 information you entered, but not the actual document.
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.
