For the notification from where’s my refund saying they have received my return and is under review and have a alert on irs saying I need to verify and others had it?

There are different types of review processes that the IRS might place you under. 

The IRS might place you on an automatic "60-Day review", with this review the IRS usually will send you a 4464C letter advising you of the delay.

You might also see a delay due to Tax Topic 152 references that your return might need additional review and could take more than the usual 21 days. This doesn't mean that there's anything wrong with your return, or that there's anything missing. For more information regarding this topic, visit the link below

There could also be a review for Identity verification. The IRS will also send you a letter for this to verify your identity using instructions located on that letter.
