I've written implementations of SHA256 and SHA512 before and I would definitely _not_ recommend doing it yourself 
The chances of introducing bugs is very high and I also don't think QB64 is a great language choice for it anyway. I could potentially see SHA getting added to the language in the future (so then you could just use it without implementing it) but probably not soon.
Your best bet by far is to find a crypto C library that can already do this (including TOTP) and use that. Several exist if you google for them and calling them from QB64 should be fairly straight forward.
