I used my last paycheck stub since I got W2 late. I see that I my wages were more on my stub than on my W2 could this be the reason it got reviewed

Yes, it could be.  But it could be other reasons as well; it's hard to say specifically.  Here's some standard IRS language regarding the CP05 notice:

We sent you this notice because we’re reviewing your tax return to verify:

• The income you reported on your return
• The income tax withholding amounts you reported on your return
• The claims for tax credits you made on your return
• The withholding claimed on your Social Security benefits
• The household help you claimed
• The Schedule C income you claimed

Normally with CP05 notices, you simply wait until they conclude their initial review and send you a letter.  They may request additional info.  They should've given you some sort of timeframe in the notice.  In the meantime, you should assemble your documents and re-familiarize yourself with the return.
