Form 8915-E

I used the Qualified  2020 Disaster Form 8915-E for tax year 2020 and elected to spread the taxable amount over three years. I am aware that TurboTax does not currently have the form 8915-F included to complete this part of my taxes. I have a personal need to file my taxes early for FAFSA and Medicare related issues. Should I go ahead and file the taxes without this form and amend later when this form is available?

 

Also, if I were to choose to repay some of this money back to my IRA...is it too late to do that for tax year 2021?...or would I still have to claim that 1/3 of my original withdrawal?

Thanks
