Sales and use permit

I have a hobby trying to turn into a business . It’s Jewelry making . Started last year.  I’ve sold a few pair here and there to friends on my Facebook.  A few at a boutique in my home state.   I’m working on a website .  I found out I need a sales permit in the state on TX.   I got that a couple months ago … but since I technically  didn’t have that last year, do I even  need to still claim my earnings and do taxes???   Or do I wait to claim this years income on next years taxes since I’m more official now with the ID ?  I’m so confused and not sure what to do.
