Retirement tax questions

@robbinsd13  Thanks!
I printed my return to file through mail. Prior to this I filled 1099-R form but in the printout, i don't see any entry referring to the amount i filled in 1099-R. Where can i find that entry on 1040 form? Or does that mean 1099-R amount is already known to IRS implying that they know I withdrew the money already?
