Question on backdoor Roth IRA contributed to year 2020 but done in Apr 2021 above income limits

Hi experts,

I tried to do backdoor Roth contribution for my spouse by first putting 6K in traditional IRA and coveting to Roth IRA soon, But i did this for 2020 year,  in Apr 2021;  so i do not have 1099R yet (may come next year).

Note:I am above income limit so do not qualify for deductions. 

 

Question is how do i report 2020 Back door Roth IRA now (for 2020 tax returns)?
