filling 2021

I flied in January and was accepted on the 10th of this month. Its been well or close to two weeks and I have not received a letter or update on WMR none. I am scared I am under review. I am unsure why it is taking this long. 

My question is. Have anyone had this problem and or is going through the something?

My last question is, If I have not heard anything back from the IRS by now I should be in the clear? 

When should I start looking for my Transcripts?
