Nice thought but you cannot amend in that way ... column A must be as filed and until you get that in the program correctly you cannot even start the amendment process.
If you had a CPA do the return then I highly recommend you go back to them and have them do the amendment. It is possible that the optional standard rate method on the OIH deduction was better than the form 8829 method.
Also are you really talking about the OIH deduction or are you referring to the Sch A itemized deductions ? You can take the optional method on the Sch C AND take the standard deduction OR the Itemized deduction on a Sch A.
