A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or another. The most common use of a TXT record is to add your site to an online search engine or to an analytics platform, which offers details about the traffic to your site. Creating this sort of a record can serve as proof that you are the Internet domain owner and they'll provide the content that you need to include as the value when you set up the record. Another purpose of a TXT record is to confirm that an e-mail message is sent by the domain owner and from a reliable server - this is the so-called SPF security, that prevents any electronic address set up under your domain to be forged and unauthorized people to send junk mail making it appear like it was sent from your own mailbox. You can include any other info that you would like to be associated with your domain in a TXT record as well.
