There is a post marked "solved" so apparently I can't ask another question on it directly:

How is Form 4952, line 4G calculated?

https://proconnect.intuit.com/community/individual/help/form-4952-investment-interest-expense-deduct...

In the post is an example of a completed form 4952. Can you do another example with lines 4d and 4e included?

Specifically, I am trying to figure out where long-term and short-term capital gains and losses from sale of stocks are entered.

Per the instructions for Form 4952

4a includes interest, ordinary dividends, annuities and royalties, but not capital gains or losses, those are on 4d. The instructions specifically say ordinary dividends but then 4b allows you to subtract Qualified dividends that might be included in 4a – what???

4d in the instructions it defines “net gain” as total gains over total losses, which is the typical definition of net. I assume this means both short-term and long-term? Does it apply only to capital gains or gains from other investment types?

4e then uses the term net capital gains as net long-term capital gains over net short-term capital losses. The term “net” generally means gains minus losses. But here does “net long-term capital gain” mean only the sum of all LT gains, not including losses? Same for “net short-term capital losses” does that mean sum of all short-term losses, or short-term gains-short term losses and the term assumes the math will be a loss?

I understand the principle that qualified dividends and long-term capital gains are taxed at lower tax rates so the point is to separate them out and allow the user to decide if they want to offset a portion of the investment interest expense against these two gains. I also understand that losses need to consider the allowed max $3,000/year capital loss carryover allowed on a different form of 1040. But the form 4952 doesn’t make sense given the terminology is not clear.
