Which income limit applies for stimulus check calculation if spouse has ITIN ?

I have an SSN with a dependent child who also has an SSN, but my spouse has an ITIN. I know that in light of the new rules, mixed status families like me became eligible for stimulus payments, for members who had an SSN.

 

My question is how do I correctly calculate the stimulus payment I'm eligible for, if I filed 2019 tax return jointly with my spouse who has an ITIN ?

 

For example, for the first stimulus payment from last year, the max income limit to receive any stimulus payment was $198,500 for joint fillers, and $99,000 for single filers. Since my wife has ITIN with whom I filed 2019 tax jointly, which limit here applies to me ?
