Thanks @MinhT1! Both my extension and return were filed through TurboTax and accepted by the IRS. Unfortunately I did not notice an option to report estimated tax paid when I was filing my return, nor did TurboTax prefill my estimated tax paid even though I filed the extension through TurboTax! Line 26 on 1040 is blank and I am due a refund on my federal return even without the estimated tax payment factored in. Do I need to file an amended return to make sure my refund includes the estimated tax that I effectively overpaid?
