Problem with receiving ADA

Hello All,
I’m absolute beginner to crypto and little bit afraid I made a mistake with buying ADA.

8 hours ago I bought the lowest package on coinmama of ADA but entered the address on my paper wallet. I realized that the address for receiving payments should be generated from Daedalus -> Receive

I still can see the amount of ADA at my account that equals to zero.

Did I make a stupid mistake? Or does it take time to process the transfer?
Thank you in advance for helping me out.
