It depends. TurboTax Online doesn't include Box 7 for 1099-OID forms. This box is usually for information and isn't needed for tax calculations. TurboTax often focuses on fields that directly impact your tax return. I realize this isn't ideal when you are trying to identify a particular OID to check.
The only other alternative is to guess the bond in question, as you suggest by comparing it to the other bonds in question as you suggest.
