Form 1116 Computation Worksheet Issue

JackSpaniel — Thu, 29 Jan 2026 14:23:22 GMT

Hi,

Turbotax is erroring out because it needs the numbers for Lines 4b(1)b and 4b(1)c as shown in the highlighted cells of Form 1116 Computation Worksheet. The EasyStep interview process does not create these two numbers, so they have to be entered in Forms mode. I had no investment interest expenses, but I can't get rid of the zeros on Line 4b(1)a, so I must supply the following two numbers TurboTax is asking for:

Line 4b(1)b: Adjusted basis of investment assets generating foreign income

Line 4b(1)c: Adjusted basis of total investment assets

Please help me calculate these numbers.

Thanks!

You should be able to delete the 0's in 4b(1) in FORMS mode.

In the Foreign Tax Credit interview, there is a screen asking if you' had any expenses' relating to the foreign income you're reporting.

You might want to step through the interview again to check your entry.

I tried but can do neither, unfortunately. I can't delete the 0 in Forms mode. I can't delete the 0 from the interview mode either - attaching a picture here which says the 0 comes from Schedule A but I can't delete the 0 in Schedule A either. Please help - I have tried everything I can think of!

I have a 0 on Line 9 of my Schedule A too, but it didn't transfer to Form 1116. Did you choose 'general category income' on Form 1116?

The 'source' for Line 9 is Form 4952, Investment Interest Expense Deduction. Perhaps you could delete this form and see if that resolves, next Schedule A and finally Form 1116.

Since we can't see your return in this forum, I'm at a loss for other suggestions. You can Contact TurboTax Support; they may be able to help by screen sharing.
