Help Figuring Out 2021 Business Taxes/Personal Ta

Hi, my husband launched his business in 2021, but he had a lot of difficulty figuring out taxes, and he needs to get caught up and pay all the taxes from last year, along with the corresponding late fees. We also need help with getting our personal taxes figured out (as the business taxes information is necessary for that). If you have availability to assist, please let us know. I know this is last minute, and I sincerely appreciate your time.
