I qualify for stimulus check for 2019 & filed independently & received refund but not stimulus check. I did not qualify for 2018 because I was claimed. The person who claimed me in 2018 has not yet filed for 2019. Did I miss out?

Hi,

So I was claimed by my mom in 2018. She has yet to file this year & she already received her stimulus based off 2018 taxes.

I filed independently this year on 4/15, my refund was approved and I received my tax refund- I have not received my stimulus. I’ve looked up the status of the stimulus a few times and keep getting “Payment Status Not Available”. I've seen that most people that have filed in April (like me) have already received their stimulus. 

My question is; since my mom (who claimed me in 2018) has not filed independently for 2019 yet, is this affecting MY ability to be eligible to receive the $1,200 stimulus payment? 

Thank you
