I took 20 mg Lisinopril a second time instead of 50 mg Atenolol. Supposed to take the Lisinopril once daily and the Atenolol twice. Am I okay?

If you are concerned then you should call poison control at (800) 222-1222.

From what I was reading, the biggest risk would be your blood pressure dropping too low (hypotension). However, taking only one additional dose may not cause that for you. Here is a pdf with more information:

I hope this helps and please report back with your outcome.
