what are you missing? Turbotax allows entering estimates for missing info which could give you a better idea of whether you owe or not. this in part depends on the accuracy of those estimates. if you owe zero use that. if you owe enter and pay that by 4/18. if you overpay you can either request a refund or apply part or all to 2023. if you underpay expect a bill maybe including penalties and interest if significantly underestimated or only interest.
