SSA-1099-SM includes amount paid in 2019 for 2018

I don't understand what you want where it says "Enter the amount in box 5 of your Form SSA-1099 and/or Form RRB-1099 received in 2018 and already reported on your 2018 return (This is not common)..  It looks like you want what I entered from my 2018 SSA-1099 form.. since that is not uncommon I think you may want something else???
