Laid off this year with severance package

I was laid off in the spring of 2023 and had a severance package for several months. I did not file for unemployment during this time (and do not plan to). My spouse is still working and my oldest child had a summer job. With this basic knowledge, I'm curious what I can do now to get a preview of what my tax situation might be? Another way to ask a more general question, what implications do layoffs have on taxes?
