What is the best way to have my taxes prepared this year?

I didn’t make very much money last year, a few thousand dollars in cash jobs that I need to report as income. I also have a small business with a vendor’s license where I report sales tax monthly. However, the cash job I have always filed annually with my husband’s taxes and this year I am not able to do that as we are going through an ugly divorce and I’m not able to get in contact with him, so I am going to attempt to file my income separately.

My issue is that my independent income is from different sources and I have no idea how to file it. Also, I know I will owe taxes on this income and I’m assuming there may be a late penalty because reading it seems that I should be filing this quarterly? I am on a very strict budget right now and finances are extremely tight, but I have no idea how to do this myself. What are my best options? Should I take it to a tax preparer? Turbo Tax? Am I overcomplicating it and is this something I could probably handle on my own?

Thanks.
