This a change from what was used as Q&A's from previous years' editions of TT for line 2a on OPM's 1099's. Your suggestion mirrors what was used and what still applies - all receivers know and should only have to know that the amount reported as 2a is what the OPM considers the taxable amount. Yes, I could mine the tax regs to find out how they calculate it (general or simplified methods) - but this has been standard for years and if the tax regs have changed - TT should alert us under the now blank "Learn More" options.
Not a tax expert - only a user of TT for 20 years
