I don't know whether this will help or just make things worse for you. I've never used the online version. I always purchase the TT Home & Business DVD, so I don't depend on what the online version does or doesn't support or allow. However, you use the words "overwrite the SE tax" in your question. I understand that the previous responses in this thread recommend doing that, but I don't actually do that. Instead, I do this: The SE Adjustments Worksheet (form "SE Adj Wks") has a line labeled, "Less other SE exempt nonfarm profit or (loss)" on line 7 of Part II of the form. NOTE: The following step won't work for you, if the online version doesn't allow you to enter anything on that line. The purpose of that line is to allow you to enter an amount to subtract from your "Nonfarm Profit or (Loss)", to reduce your SE income (for SE tax purposes). I enter the total of my outside-of-the-USA SE income there (which is already on line 1a in the same section), which reduces my income (for SE tax purposes) to zero, and that effectively zeroes out the SE-tax-owed on the return *without* having to override anything. This tactic is consistent with the USA-UK Totalization Agreement, under which I pay no USA SE taxes as long as I pay the required amount into the UK National Health System, their equivalent of Social Security. This past year, I also had to make sure that TT did *not* generate a deduction for the SE tax I might have paid, or else that deduction would show up on the filing, even though I paid zero SE tax. I don't recall exactly where, but at one point, TT asks you to check a checkbox, if you want to use the SE tax deduction: You *do not* want to check that checkbox when it is first shown to you during the "interview". If you inadvertently check it, going back and unchecking it later has no effect (possibly a bug or oversight in the software). I had to run the whole program again from scratch to get rid of the deduction. One last concern: you'll notice in my previous post that I found no way in the program to annotate for the IRS my use of the "Less other SE Exempt nonfarm profit (or loss)" line. When I use this tactic, I am required to attach the UK form, "HMRC form CA3940, Certificate of Coverage" to my return, and I suspect that's something you cannot do, if you use the online version. I apologize if this isn't the help you need. I'm not a TT expert or consultant: I learned all this from other forum posts and a lot of head-scratching and trial-and-error. The fact that TT has perennially refused to offer a straightforward way to manage this sort of SE reporting is the primary reason I'm planning to eschew TT and instead trial the new IRS Direct File option next year.
