TT indicates an error, and that on the worksheet for Form 1116, I need to enter the Basis of Total Investment Income. I have no idea what I need to do. I can't just enter $0. I didn’t have to do it last year- even though I was over the $300. The foreign taxes are from simple Vanguard Mutual Funds that generated the foreign taxes. But I don't know where to find the number TT wants. Thank you sincerely for any assistance.
