How do I file previous 1099 forms from 2021 -2022 on 2023 taxes??

Only forms for 2023 can be entered on a 2023 tax return.

You can't include them on 2023.  You have to file each 1099 on the right year.  If you filed 2021 and 2022 returns you need to amend them to add the 1099.  What kind of 1099 did you get?  1099NEC, 1099R, 1099G, 1099 INT etc.

You can not put them on your 2023 return. You will need to amend your 2021 and 2022 returns.

 

If you want to make changes or add a document to a tax return that has already been submitted, you should follow these guidelines. 

• You must first wait until the initial return is completely processed. 
• You will have to use the same TurboTax account that you used for the original tax return. 
• Once you begin your amendment, you'll see your original return.  
• The refund calculator will start new at $0 and only reflect the changes in the refund or tax due 
• Only make changes to the areas of your return that need amending. 
• You have three years from the date you filed your return or two years after you paid the tax due (whichever is later) to file an amendment
