A TXT record is text in free, human-readable form, that is associated with a domain name as a DNS record for one purpose or other. The most typical use of a TXT record is to add your site to an Internet search engine or to an analytics platform, that provides info about the targeted traffic to your website. Setting up this kind of a record can serve as verification that you are the Internet domain owner and they will supply the content that you need to include as the value when you set up the record. Another use of a TXT record is to validate that an email message is sent by the domain address owner and from a trusted server - this is the so-called SPF security, that helps prevent any electronic address created under your domain name to be forged and unauthorized people to send unsolicited mail making it appear like it was mailed from your own mailbox. You could add any other information that you would like to be associated with your domain address in a TXT record as well.
