Are these burns? How serious is this?

My tegu was spending a lot of time under the light earlier in the year. He just recently shed to reveal this. I assume it's burns from just sitting under the light for hours and being super lazy.

Is there anything I should do to help? I moved the light further away to try and prevent that happening again

I would say this is indeed a burn. Can you show your light setup? A common way that larger lizards get burned is that they only have one strong basking light, and they try to warm their whole large body by sitting directly underneath it, not understanding that this will burn them. A fix to that is using several less powerful basking lights in a cluster, say three lights over the same area so the heat is more widely distributed instead on concentrated on one small spot

I just have the one light right now and would be really hard to do more

Sounds like you might need to change your setup then if that's the case. Moving the light up higher won't fix the concentration problem that caused the burn and your tegu likely won't get sufficient heat if you do, they should be able to warm their whole body on their basking spot, hence keepers use clusters of lights when they get big. There is no single bulb setup that will be sufficient for an adult tegu and not cause burns
