You are confusing several things. A $30 tax credit (which is a direct subtraction from taxes due) has nothing to do with the Standard deduction (which is a subtraction from income, before the taxes are calculated).
return was not accepted by the IRS
Accepted means received for processing by the IRS. It does not mean Approved, which is a later step.
and yet it was approved by the Fed Review
Do you mean the Turbotax Federal review? That is just a general check for things like inconsistencies. TT does not and cannot Approve the amount of your refund; only the IRS can.
Given all that, it's not clear what you are asking. Did the IRS accept your return for processing, but then deny or change the amount of your refund? Or was you efile rejected for processing? And what $30 credit do you mean?
