Filed taxes with another company

I have filed by taxes with another company earlier this week and they told me that I need to pay even more for my taxes, even though I was here just for 3 months of the 2021 tax year. Your calculator told me that I am due a tax refund so I would be getting money, as opposed to needing to pay money. Is it possible for me to change something so that I can file with you and get a refund instead? H and R block have already submitted my file which I think is the problem...
