A TXT record is text in free, human-readable form, which is associated with a domain name as a DNS record for one purpose or another. The most frequent use of a TXT record is to add your web site to an online search engine or to an analytics platform, that provides info about the traffic to your website. Setting up this sort of a record works as proof that you're the domain address owner and they'll provide the content that you should include as the value when you create the record. Another purpose of a TXT record is to validate that an email message is sent by the Internet domain owner and from a trusted server - this is the so-called SPF protection, that prevents any electronic address created under your domain to be forged and unauthorized individuals to send junk e-mail making it look like it was mailed from your own mailbox. You can include any other info which you want to be associated with your domain address in a TXT record as well.
