Same setup on the cool side of the tank reads about 80 degrees. I’ve read to use a UTH to help radiate heat upwards on the basking spot, if this isn’t recommended, I will just worry about the air temperature inside the tank.

Any thoughts on how I should proceed?

Oh and as a reference, I’m currently using a 20 gallon long tank since she’s fairly small still.

Ah I see. That's a good idea in a glass tank because they hold heat very poorly. Wooden (sealed) and plastic enclosures hold heat and humidity extremely well so a UTH would not be required in that scenario.
