For Vanguard, I saw one 1099-DIV footnote re: their 2019 tax forms:
"*Real estate investment trusts (REITs) generally can’t calculate their taxable earnings until after
the end of the tax year. For this reason, we request an extension from the IRS each year to
mail completed Form 1099-DIVs for Vanguard Real Estate Index Fund."
______________________________
And the 2020 "expected dates for 1099-DIVs is 19 January 2021...except for REITs, where 2/18/2021 is "expected", but not necessarily locked in for that date. I have no idea when they issued them for 2018.
