So bad at adulting

I posted yesterday about which credit card is best. Here’s the update. So I went and tried to apply to capital one like y’all recommend and they asked me for my annual salary. I’ve only made 1543$ this year. So that’s what I put. Of course I got denied. Did I do that wrong ? I mean I get it looks bad but I can just guess my yearly salary because I haven’t worked there for a year yet. I’m clueless

Update: thanks y’all!! I applied again and did the math equation and got accepted!
