My Capital Gain amount is not being added to my income in Part 5 of the Capital Gain T form.

What form/schedule number is the "Capital Gain T form" you're referring to?

Your capital asset sale is reported on form 8949, then to Schedule D (if you received a 1099-B, you may be able to skip form 8949).  The resulting gain or loss goes to line 7 of form 1040. The capital gain tax is calculated on the "Qualified Dividends and Capital Gains Worksheet (or the Schedule D worksheet).

None of these forms have a Part 5.

I don't know the actual answer...but for those who might be able to help?

A form, that perhaps only a few of us have heard of..

Maybe it is the IRS "Form T (Timber)"    ??
