Needs to come apart and be inspected.   Might be something loose or broken in the shift selection mechanism on the right side.

The shift “star” detent is on the clutch side at about the 5 o’clock position. Sometimes they will come loose.

Check the points on the shift shaft that move the star  They tend to get rounded and cause your problem

My 20 350 had a hard time going into gear and was doing something similar to what you are describing. The shift star had some burrs on the edges and the points were rounded a bit. The shift shaft was rounded like the Factor E said here, plus I think it was a wee bit bent. So I replaced those 2 items and it shifts like butter now. Luckily you don't have to split the cases for either of those two parts. I was replacing a crank so I did have the cases split when I replaced mine. Should be an easy fix for you.
