Question about DP02_0011PE

Hello, Someone in the Census Slack channel suggested I post a question here.  I hope this is an appropriate forum.

The following api call produces valid estimates for single person (no spouse) households in 2019:
https://api.census.gov/data/2019/acs/acs5/profile?get=NAME,DP02_0011PE&for=county%20subdivision:*&in=state:25%20county:017
But returns only -888888888 for 2020:
https://api.census.gov/data/2020/acs/acs5/profile?get=NAME,DP02_0011PE&for=county%20subdivision:*&in=state:25%20county:017

I checked the 2020 change guide here:  https://www2.census.gov/data/api-documentation/2020-5yr-api-changes.csv but can find no reference in a change to this variable.  Can anyone direct me to a new variable for this data or let me know if it's been deleted and I just can't find the change log?

Thanks very much...Jim C
