Do you mean a 1099G for unemployment?
You will have to enter a 1099G that is issued by your state.
Some states will mail out the 1099G. Or you might need to go to your state’s unemployment website and use the password, etc. that you have been using to certify for weekly benefits to get your 1099G from the state’s site.
Enter your 1099G in Federal>Wages & Income>Unemployment
Go through the screens very carefully, making sure to enter any federal/state tax you had withheld from the unemployment.
We'd love to help you complete your tax return, but need more information. Can you please clarify your question? When you say 1099 benefits, if you mean from Social Security on Form SSA-1099, then see: Where do I enter an SSA-1099, SSA-1099-SM, or SSA-1099-R-OP1?
Otherwise, @xmasbaby0 is correct. If you are referring to unemployment or paid family leave, see: Where do I report a 1099-G for unemployment or paid family leave?
Each state is taxing or not taxing unemployment benefits as they see fit. TurboTax is up to date on each state. Just enter your details and TurboTax will handle the rest. For more details, see: How is my state taxing unemployment income?
