"Enter the code from your email address at: gmail.com" I think steam doesnt know my email anymore

[Rokuro240]

i know the login for my steam account and password but steam guard keeps asking for a code which is weird since i have it turned off but its not sending any emails I've waited 30 mins. I've also waited an hour for it to send the codes via email they never sent I've checked my spam and trash folder nothing I'm honestly lost and I'm afraid to log out on this laptop I'm sign into now
any help would be appreciated
