@JanSal I don't know what the IRS letter says about Schedule SE, or why it even refers to Schedule SE. Schedule SE line 26 is a cap on the amount of tax that you might be able to defer, but you might not be able to defer that full amount. The amount that you can actually defer is calculated on a worksheet. The amount that you actually did defer is on Schedule 3 line 12e. TurboTax shows it on that line because that's where the IRS instructions say to put it.
