Line 8 on the 1040 comes from line 10 of Schedule 1 (1040). Please go to Schedule 1 and tell us what numbers are in which lines (i.e., line 1-7, lines 8.a though 8.z). This will tell us where the $12,280 is coming from.
1 - 0
8f - 10,100
8z - 180
I did make 180 staking crypto so line 8z makes sense to me.
That's not clear. How did you enter your return? Did you enter information about you and your spouse as if you were going to file Joint, then switched to Separate? That causes a lot of leftover data in your return which can confuse everything. Or did you enter only the most minimal amount of data about your spouse?
I started my return saying that it would be married filing separate and that my wife wouldn't be filing a return this year. We did this because of her IBR. I can't remember if I tried to see what filing jointly would do after seeing the big drop in my refund or not but when I got to personal it shows married filing separately.
