@Lily Yu,
I'm about to dive in and enter my 1031 exchange from 2021, where I sold a coop in NYC and bought a rental house in Maine and a Delaware Statutory Trust share. Reading this thread has been quite beneficial.
On the topic of e-filing, I'm concerned that my NY State return might be non-standard and flunk the e-file test. That would be a very bad development, since NY absolutely requires everyone to e-file. I still have my 2020 NY State return sitting on my desk because the TTax e-file failed. I'll cross that bridge after I get 2021 return done.
