Thank you very much @BillM223 , that's very helpful!
On your response #2 - What's the best way to go about requesting the waiver? I am seeing online that there's mainly 2 initial options to go about this - The first one seems to be through the Taxpayer Advocate Services (https://www.taxpayeradvocate.irs.gov/contact-us/), and the second seems to be via Form 843. Which one would you recommend?
Also, should I be re-attaching copies of all of my amended / previously related forms, received letters, and a personally written summary when reaching out to the IRS via mail?
Thank you!
