What do you mean by "verifying requested information"? Did you get a notice from the IRS asking for more information? If so, follow the instructions in the notice for what you should do, and be sure to respond by the deadline in the notice. If the instructions in the IRS notice aren't clear, call the contact number in the notice. Send your response by certified mail, with a return receipt, so you will have proof that the IRS received it.
Do not file an amended return unless the IRS notice tells you to do that. If it does tell you to file an amended return, send the amended return to where the notice says to send it, which may be different from where you would send it if your were filing it on your own initiative. Include any other information or attachments that the notice says to include.
