@twinkles777 - the 2nd would come automatically. if it doesn't, there is a 'settle up' section on the 2020 tax return, so worst case, you will capture it there as a credit which will increase the refund or reduce taxes owed.
look at line 30 Form 1040 when you complete the return - that is where any additional money owed will be reflected.
what is the date on your screen shot? it looks like an article posted BEFORE the 2nd stimulus law was passed. As noted above, the two stimulus payments works differently for those who passed in 2020.
