Tierney Sneed for TPM:

The Census Bureau has identified issues in the data from the 2020 decennial census that will take an additional 20 days or so for it to fix, and thus delay the release of survey’s apportionment data until after President Trump leaves office, TPM has learned.

According to a person inside the Census Bureau, the additional time it will take to reprocess the data in question has pushed back the target date for release of the state population counts until Jan. 26 – Feb. 6.

That would mean President-elect Joe Biden will be in the White House when the Census Bureau delivers to him the numbers for him to transmit to Congress for the purposes of determining how many House seats each state will get for the next decade.
