@lfcook11 (and other people coming here in the future) If you remember the date and the amount you sent, you can use a block explorer search engine.

I Googled "search bitcoin transaction by date" and found this Stack Overflow answer:

Suppose I want to search for a transaction of exactly 445 BTC in the date range 27 July 2013 and Aug 3rd 2013 ... is there an (online?) tool that has this kind of search capabilities?

Blockchair allow you to query the bitcoin blockchain with lots of parameter such as date, BTC output amount, fee amount etc...

Here is your request: https://blockchair.com/bitcoin/transactions?q=time(2013-07-27..2013-08-03),output_total(44500000000)#
