You cannot correct it now. You were only asked if you received the 3rd EIP payment---the one for $1400 per person. If you really received that payment ---but said you did not--- then the IRS will catch your mistake and reduce your refund by the amount you put on line 30 by mistake. Expect that to delay your refund--you will be waiting longer.
