EVERYONE's tax return is on a Form 1040. There have not been any 1040EZ or 1040A tax forms since the forms and tax laws changed for 2018 and beyond. If you print out your return it will be on a Form 1040.

Many forms and schedules are not yet ready. When the IRS/state has finalized the forms you need then you will be able to file. Click Review to see what you have to wait for. The IRS is not accepting returns until January 27, so there is no hurry to file now. Filing now would not result in an early refund.
