Retirement tax questions

There are some foreign pensions that are not taxed under rules preventing double taxation.  I used to be able to enter the pension under Retirement income and set the taxable amount to 0, per the verbiage in the treaty. Previously I could use all 9's or all 1's for the TIN, but that is not working this year. Using Other Misc Income makes the whole amount taxable, which is not the correct treatment. I am concerned that I will either have to start using a program other than TurboTax or file manually unless there is some way to work around this.
