Usually we file our married filing jointly return at about the same time as we file our son's return. 2019 was a year of change; our son graduated high school, could not find work, ended up job training with Voc Rehab (and earning minimum wage while doing so), and enrolled in college, starting classes this spring. We assumed we could claim him as a dependent, and so did he. We filed his return accordingly, and after a question of our own got answered, went to file our return. The TurboTax software informed us that since he wasn't a student in 2019 - even though he was for 2018 and is now for 2020 - and since he made over $4200 at Voc Rehab, we could NOT claim him as a dependent, even though we provided pretty much all his support/living expenses and he lives here with us at home. So OUR return got filed with him not on it as a dependent, but HIS return got filed early (his refunds for federal and state have already both arrived) with him listed as "(we) can claim him as a dependent". The question becomes, do we need to file an amended return/1040X for his taxes? federal and/or state (South Carolina)? We filed with Deluxe and he filed with Free/Basic, so I wasn't sure which "product" to put in the tags, but we both filed online. Our son and I did the filing for his taxes together, while I did the filing for the return with my husband.
