How can I change my payment date?

[SidneyP · Accepted solution]

You are unable to change your payment date in Turbo Tax once you filed your return and it has been accepted but you can cancel it and then make other payment arrangements with the IRS. 

Federal Tax direct debit payments can be canceled up to 48 hours (midnight, Eastern time) before the date you designated the funds to be debited. To cancel your direct debit transaction, call (888) 353-4537.But please wait 7-10 days after your return was accepted before calling.

Can you tell me when do I expect a refund 

[ChondelLO]

It can take up to 21 calendar days after your return is accepted before you receive your refund from the IRS. You can check the status of your return by using the Where's My Refund Tool located at the IRS website.

State returns are processed by a separate entity and therefore have their own processing time. To track your state return, please click the link below and select your state.
