Formula would return bills (Rent, Utilities, etc.) for matched date (5/1/20) 

What formula do I use to list items matching a date and separating each one with a comma? \*list not in different cell but kept in the same, results just separated with comma \*Google Sheets Thank you!

In others "words":
[Display all matching values in one comma separated cell](https://stackoverflow.com/questions/19561213/display-all-matching-values-in-one-comma-separated-cell)
BUT answer didn't work.

Basically the opposite of:
[Comma separated list into matched columns pairings](https://stackoverflow.com/questions/57593084/comma-separated-list-into-matched-columns-pairings/57698827#57698827?newreg=641a10783ac84c2786bf1092d787442e)
