"There is no way to enter Form 4797 – Part II information without doing an override,"
Really?
-----
Method for 2018 TurboTax--
First get into Forms mode (this means you're using the desktop program, not Online).
Then open Schedule C Give it a name (Trader)
Set Line 7 Accounting Method Other (MTM) [[or as you wish]]
Click the upper Quickzoom button Disposition Worksheet
Give it a description ( "Trading outcome")
In Part 1 A. enter (as per IRS instructions) "Trader-see attached".
The red boxes for Property A will open.
Fill in the red boxes with your year end results.
For Type of property Choose H ( Ordinary ) [[or as you wish]]
Your 4797 p1 will be generated.
Open your form 4797 and complete Line 1 (one of the few fields that will take more than 10^7 dollars)
Open Form 1040 Click Print on the bottom of the screen.
The income appears on your Form 1040 Line 8 [[ now Schedule 1 Line 4]]
Note: When the tax return is printed, Schedule C will not be included.
If you want Schedule C you'd have to complete some other lines there.

The attachment is the details of all your trades for the calendar year.
Unless 2023 TurboTax is a lot smarter about attachments,
that means you'll have to file a paper return anyway.
