I have a form 1065 & I sold 8 units. So I marked I disposed of a portion of my interest in my partnership during 2020 and then marked sold partnerrship interest.Correct?

No.

As a partner in a partnership, you should be maintaining your tax basis in this investment.

What you need to do is determine your basis based on the number of units you have.  Then multiply that by the 8 units sold.  This will give you your gain.

You would then report this on form 8949 and Sch D based on the time you held the units.
