Turbo tax says my return is expected today , will it come for sure today ? If so what time ?

The date for the tax refund to be received and reported by TurboTax is only an estimate.

Go to the IRS website for the actual status of a federal tax refund - https://www.irs.gov/refunds

After the tax return has been Accepted by the IRS (meaning only that they received the return) it will be in the Processing mode until the tax refund has been Approved and then an Issue Date will be available on the IRS website.

When i put in all my information like tax year, filing status, SSN and tax amount it says the tax amount is incorrect, and I don’t know where to find the correct amount.
