Paid GoDaddy Mail Account not authenticated

Have had a paid GoDaddy mail account for MANY years.  Starting yesterday sending from this account to a gmail account, a red circle with question mark inside started appearing on the recipients e-mail at the 'from' account - that was ME, the sender.  Google apparently wants DKIM and SPF authentication but I can find nowhere to do that.  Please tell me how to get there and then how to fill out the forms for each.  I know they will be TXT but not what GoDaddy wants there.  Thanks
