Did you get IRS letter 6419 saying how much advance they sent you? You should each get a letter for half.
You qualify for 3600+3600+3000=10,200. Then minus the $3,000 you got gives 7,200 for line 28. Don't know how you only got 2500 on line 28. Then it doesn't make sense you owe 1500. Double check your bank account. The IRS shows they sent you more.
