Dramatic change in amount owed vs. amount due.
I have been preparing my own taxes using turbotax for years. This year preparing my taxes I entered my W2 and it showed I was due a refund of around $700. I then entered my wife's W2 and it swung to us owing over $10k. I removed both W2s and entered my wife's first. It showed refund due of around $300. Enter my W2 to the mix and now we owe over $10k again. I did all of the calculations for what I would owe tax wise and what my wife would owe tax wise both filing jointly or married filing separately. All the numbers show that we have paid more taxes than required and we should be due a refund of just over $1,000, but the turbotax software continually shows federal due of over $10k when I input both our W2s and I cannot make sense of why this is happening. Is this an issue with the software or does anyone have help with what is going on here?
