Tax Help for (Very) Small LLC

Hi all, my husband and I sell books on Amazon and are very small (no 1099K form) LLC. Most of what I find online for Amazon Seller tax help seems to be for bigger sellers than we are.

Is anyone a small or personal seller and can give some advice or guidance on filing? Should we be getting something like TaxJar or Avalara to do our taxes? Or is filing through something like FreeTaxUSA possible with our situation?

We’re too small (not enough resources) to just hire an accountant to handle it for us.
Thanks in advance!
