I suspect that this is referring to an error message related to the IRA Contribution Worksheet that is mistakenly referring to line 27 instead of line 26, a line that was renumbered between 2019 TurboTax and 2020 TurboTax without the error text being correspondingly updated.

Line 26 is related to an excess Roth IRA contribution carried in to 2020 from 2019, a value that is either user-entered or transferred in from the previous year's tax file.

The Roth TSP is not a Roth IRA, so this has nothing to do with the Roth TSP unless you mistakenly entered something regarding a Roth IRA in a previous year thinking that the Roth TSP was a Roth IRA. Perhaps on your 2019 tax return you mistakenly reported as a Roth IRA contribution the amount reported with code AA in box 12 of your W-2. If so, you probably need to amend your 2019 tax return to correct the mistaken reporting of an excess Roth IRA contribution that you probably did not make.
