I have a JD 5205 that won’t turn over. Turned key on and jumped across solenoid and it turned over but didn’t start. Any suggestions.

Battery? Battery cable connections?

More details would help get you more accurate replies. Side note. You can't start that tractor by merely turning the key on and "jumping" the starter. It has a bypass relay that prevents ignition circuit voltage voltage from reaching the injection pump. (maybe you didn't know that)

Yep and that circuit has some known issues with a cold start thermistor that shorts, blows the fuse and won't start. Check all of your fuses.

Dealing with same thing right now on 2004 5205. Today the normal beeping when turning the key on that has been intermittent would not make a sound but if I pushed on the hood/dash it would start beeping and the gauges would cycle. When key fully turned to crank just a click. Used it and cranked several times earlier this morning. Went back mid-morning and just the click. Battery good. Not the cold start issue with blown fuse. Wondering if is a short. Tried looking at wiring. No obvious issues found.

Last time it did this resting voltage around 12.5 volts. Have had no issues slow cranking when this issue not present. When could get it to go through the beeping series the blinkers, flashers and headlights all work and headlights are bright even without tractor running.

This is testing voltage where? At the battery? at the starter? at the key switch? What counts is the voltage at the start signal wire on the starter solenoid. Have you checked it there?
First thing I would do (if you haven't already) is get rid of the plastic cover over the starter. Locate the start signal wire stud on the solenoid. Tractor in park, take a small jumper wire and jump that stud to battery positive cable stud just above it. Does the starter engage every time? If so, the battery, main cables, and starter condition should be good to go. Now check the voltage at that terminal when attempting to start with the key. Do this when the starter works, and again when it doesn't. Compare the voltage readings at that point and you might have some information to work with.
