I have foreign interest income and tax on this interest that is not reported on any 1099-INT. How do I get TurboTax to generate a Form 1116 (it is not at present)?

Is this from a foreign bank and if so did they provide a statement?

Yes, and I have bank statements.  I know what the interest is and the foreign tax assessed on the interest.

The 1st thing is to report the interest.  Bring up a blank 1099-INT and type in the data in USD. Create as many as necessary. 

Next is the credit. If the total interest is less than $301 if filing single or less than $601 married filing jointly, then TT should insert the interest on line 48 of form 1040. If it is there, then you are done. If the amount exceeds the limits, then you will need to go "Foreign Taxes" and initiate the foreign tax credit interview which will calculate the credit.

Thanks, but the instructions for Form 1116, say Form 1116 must be filed if you did not receive a 1099-INT reporting the interest, even if the foreign tax is < $601 for married filing jointly.
