For the next year, I am in Singapore under employment for a foreign firm from 7/31/2019 to 12/31/2020 which is 526 days, but safe harbor only applies to at least 546 days. If I was outside of California before 7/31/2019 on vacation in different countries, or if I am continuing to stay in Singapore for 2021, can any of these days count for Safe Harbor when filing 2020 taxes? Thanks for the help.
