A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or other. The most common use of a TXT record is to add your web site to a search engine or to an analytics platform, that offers information about the traffic to your web site. Setting up this sort of a record functions as proof that you're the domain name owner and they will supply the content that you ought to include as the value when you create the record. Another purpose of a TXT record is to confirm that an e-mail message is sent by the domain address owner and from a trusted 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 look like it was sent from your own mailbox. You may include any other info which you want to be associated with your domain address in a TXT record as well.
