Checking if any value in Column is equal to Todays Date

I'm working in Google Sheets and I am trying to determine if any value of dates listed in the column is equal to Today's Date.

I have tried using the COUNTIF formula the ISDATE formula and the IF formula against the value of TODAY() and nothing seems to be working right.

=IF('Invoices-Quickbooks-Data'!L:L,ISDATE(TODAY()),true)

This formula actually works the best for me. I would expect it to calculate if any of the values equal Today's Date. Ironically this tells me that the answer is TRUE even when none of the dates actually match Today's date so I am not sure what is going on.
