Yes! If you (or your parents) are married but have filed taxes separately, you’ll simply need to look at each of the two tax forms and add the numbers together.
For instance, if the question asks for how much your Adjusted Gross Income (AGI) was as a couple, you’ll need to look for your AGI and your spouse’s AGI and then sum the two figures together. If your AGI was $20,000 and your spouse’s AGI was $30,000, then your total AGI (your final answer to the question) would be $50,000.
