ITR Filed Status

Hi everyone, i have doubt in income tax return. i have filed ITR 1 for AY 19 -20. i sent through Post to CPC bengaluru. after 5 days i have received message like that we have received your ITR will be processed. then after 5 days i got one notice from IT department 143(1) intimation notice in which no demand or any query did not ask. it is stated everything matched with IT computation. then i went to login it is shown ITR processed. E verification is also has verified. but final return is not showing. it is showing this is not proof of having filed return. now what to do friends. pls help me to further proceed. do i have to submit any rectification?
