It's when you reach Catalina that there's the big break of not being able to run older 32-bit applications (which is why one of my Macs is still on Mojave). Mojave is also a safe incremental upgrade for most users. I believe every Mac which ran Sierra is capable of running High Sierra, and it shouldn't render any older software incompatible. In the short-term, you might consider upgrading to at least High Sierra. The developers have given no indication of a similar end of support for High Sierra or Mojave, but I don't know if they will. When version Quicken Mac 6.0 was being developed, the developers announced several times that that version would require at least High Sierra.

It's always possible - well, it's inevitable - that some future update to Quicken will require a newer OS. But unofficially, it still works on the two operating systems before that, Mojave (10.15) and High Sierra (10.14) I run my Quicken on a computer which is running Mojave and experience no problems. Officially, Quicken says they support the current and two most recent operating systems: so Monterey (12), Big Sur (11), and Catalina (10.15).
