Where do i report a 1099 o the form?

What type of Form 1099?  There are almost two dozen different types ie 1099-MISC, 1099-NEC, 1099-B, 1099-R, 1099-S, 1099-INT, 1099-DIV, 1099-G etc.

I received a 1099-O. Where do I report this income on the 1040?

Assuming you meant a 1099-OID (Original Issue Discount)...

 

When you purchase a bond or note at a discount, you'll get Form 1099-OID (Original Issue Discount). The discount is taxable interest over the life of the bond, which gets reported every year you hold the bond, even if you don't actually receive any interest.

 

Follow these steps to enter your 1099-OID in TurboTax:

1. Open or continue your return.
2. Navigate to the 1099-OID section:
   • TurboTax Online/Mobile: Go to 1099-OID.
   • TurboTax Desktop: Search for this exact phrase (we recommend you copy/paste from here): 1099-oid original issue discount. Select the Jump to link.
3. On the Miscellaneous Investment Income screen, select the first box for Form 1099-OID.
4. Follow the onscreen instructions.

To remove an unwanted 1099-OID, follow the first couple of steps. This will bring you to the Form 1099-OID Summary screen where you can select Delete next to the unwanted 1099-OID.
