Just noticed the following errors in postfix on a centos 7 machine. How do I fix them?

You’ve modified master.cf to add those…so, undo that change.

So, that smtps line is different from what the Virtualmin installer sets up. Not sure how you got there.
I believe our default looks like this (though I only have quite old mail servers at the moment to look at, and it’s possible our defaults have changed in some small way since they were installed, I dunno):
smtps inet n - n - - smtpd -o smtpd_sasl_auth_enable=yes -o smtpd_tls_security_level=may -o smtpd_tls_wrappermode=yes
The line you have is normally in the file, but commented out, on a fresh CentOS 7 install (and we leave it commented out and just add ours during the virtualmin-config stage of installation.
I see the submission line, which I think we also add, so I don’t know how you got where you are. If you didn’t have any of our config, I would assume install didn’t complete (Postfix is one of the last configs to get modified, so it may have looked pretty normal all the way until toward the end…still would have been a red X, or at least it would have bailed before all items completed). But, since you have some of it, I assume it’s just been changed since install to remove our line and uncomment the original line. You’ll have to figure out why/when, I guess. This isn’t a security sensitive change, so I can’t imagine it’s indicative of anything dangerous…but, somebody changed it, so kinda weird, if you don’t know why it’s been changed.
