Why did my Federal refund decreased ?

every year is different from taxable income to the amount of taxes already paid in. we can't see your return. 

thats odd because yestrday it was higher.. now its less. I thought maybe it was a glitch or my phome was messing up. But after restarting my phone and all.. it atill managed to say the same it went down. Something that usually doesnt happen

The refund will continue to change until you enter all your forms and information and complete the final review. TurboTax will recalculate your refund every time you add more information to your tax return.
