[Help...]What should I do if I still did not get my 2019 tax refund?

I still have not got my refund from 2019.. I mailed in my paper return in July 2020.. The where is my refund tool does not show any information... I know there has been delay processing mailed in returned at IRS due to covid but it's almost a year since I mailed in.. I feel very frustrated.

 

I did not get my second stimulus check because I guess it depends on the 2019 tax return... 

 

Should I call IRS about the refund? What should I do?

 

Thanks...
