I have 2 separate !099-INT from the same bank but for correct different amounts. Do I input separately or did I manually add them up and insert once?

Are you saying that one of the 1099-INT is a corrected form?  If one form is a corrected form, only enter the correct form.

 

If one isn't a corrected form, and they both have all of the same information except for the amounts. It's your preference, you can add the amounts together or you can enter both separately.

 

To enter your 1099-INT follow the steps below:

 

1. Launch TurboTax
2. Select Federal and Wages & Income
3. Select Add more income
4. Select the dropdown by Investments and Savings
5. Select  Interest on 1099-INT and follow the prompts to enter the interest that you received.

 

Refer to the TurboTax Help article Filing Tax Form 1099-INT: Interest Income for more information.
