Where on 1040 for 2017 is my RMD entered? I searched the tax return by my RMD amount and didn't see it anywhere. On which line of the tax return it appears? TY!!!

I need to show to a management co. WHERE on my 1040 for 2017 is entered my RMD?  I know it's there because the person doing my tax return did enter it but I don't see it and the person isn't available.  It would help me a lot if I knew exactly on which line of the 1040 it's always being entered.  Thanks ever so much!
