It's likely it would double up so you should first delete the current 1099 Composite-
You will want to start with deleting the original ones.
While in your return, type “1099” in the Search box and then select the “Jump to” link. This will take you directly to the 1099 Summary screen. Select Edit or Delete next to the 1099 you want to change or delete.
If you’re deleting a 1099, answer Yes when you’re asked to confirm the deletion.
Then import the revised 1099's into the program:
You can securely import your 1099-B, 1099-DIV, 1099-INT, 1099-OID, or 1099-R into TurboTax, provided your broker or financial institution participates in our TurboTax Partner program.
When you get to the place in TurboTax where we ask if you received that form, answer Yes and we'll give you the option to import.
You can also jump straight to that section by searching for the 1099 form number in TurboTax and then clicking the Jump to link in the search results.
Tip: When selecting your financial institution or brokerage from the list, be sure to select the right one. For example, several participating partners' names start with First National Bank and if you select the "wrong" First National Bank, you won't be able to import.
