CPA for Massachusetts Tax Prep and Multiple Past Year Fixes

I’m looking for a CPA who’s ready for a challenge. I’m a media professional with a big tax mess on my hands. Last year I finally filed by 2015-2018 taxes and have been met with messages that there were problems that I don’t understand. My 2020 and 2021 taxes have not yet been done. I have had freelance work and K-1 taxes every year. In 2020 the partnership sold a property (in NY, I live in MA) and dissolved – I paid estimated taxes on that at the time of sale but don’t know what to do from here. I bought a home in 2021. And there is an embarrassing mess of independent stock trading that I did on the side. As an adult with ADD, my taxes have been my greatest stress and burden. I need a qualified CPA who’s knowledgable on these issues to help me out of the weeds!
Thanks for taking the time to read my post. I look forward to hearing from you!
