filling out Schedule D treating royalties from patent as capital gains

In 2024 I received royalties on a patent I had with my former employer, reported on a 1099-MISC. The employer stated that an analysis of past IRS directives indicates this should be treated as capital gains on a Schedule D.

 

This also happened in 2022 and I got some help from this forum back then. So I just need to repeat how I filled out the Schedule D like I did back in 2022, but I can't figure out how.

 

I need to enter $4133.33 into the box in the schedule D where it says Part 1, line 3 column (d), and $0 into column (e) (cost basis). When I try to do this it says "select an existing 8949" but it appears there is none.

 

So I guess I need to create an 8949, but if I could get some advice on that plus the big picture (maybe I need to enter more numbers or check some boxes somewhere)
