Code 9021

[xmasbaby0]

Not sure what you mean by "child refund"---are you referring to a child-related credit you did not get?   Code 9021 refers to a math or calculation error made on your return.   Something you entered may have been entered incorrectly.  Or was there a mis-match between income you entered and income entered by an employer or client who paid you?    TurboTax's calculations are accurate--but they are based on the data you entered, so you may have entered something incorrectly, resulting in the 9021 message.    Double-check your own data entries.
