1095-A Form

hey everyone, im trying to file my taxes but whenever i load up a 1095-A form, its saying i owe $1400? im not so sure how this is possible. I had been buying my own health insurance for a few months and got a new job in October and cancelled it since my employer provided me new benefits. Any idea as to how I can fix my tax return to not pay this outrageous fee? My return was only going to give me around $150 anyway please help! I cant afford to pay that debt and I dont even know why its there
