Why did all my return disappear after I put my IHSS W-2?

I worked a regular taxed W-2 job most of the year but the last month I did IHSS and got a check of about $1200 in total for a couple weeks of work. I had put my W-2 of my other job and it was about $24000 gross annual income. I was going to get a few hundred back on my return but after I inputted the small IHSS check my whole return disappeared and it says I actually owe $1 for federal taxes. I'm worried about next year's taxes because I've been working fulltime with IHSS now for 2 more months and I have had much bigger checks. Am I going to owe a lot of money next year? I am not a live-in provider. I go to my own home and sleep.
