Retirement tax questions

So which line on 1040 or Schedule 1 does the income show up?  Should be somewhere.  Like Schedule 1 line 8 as Other Income?  Oh you said you don't have Schedule 1.  Cant imagine how it got on Estimates except that is only to prepare the estimates for 2020 next year's return and doesn't affect your 2019 return.  Did you only enter it in the Estimate area?
