How to calculate the government interest of ETF BIL ?

If the ETF BIL has a 98% of Income From Exempt Federal Securities in MA.

 

In Turbotax interest/dividend income,  there's a place to enter US Government interest.

Enter the amount of dividends reported on this 1099-DIV from MERRILLLYNCH that represents interest from U.S. Government obligations.

 

If the total BIL dividend is $1000, what should i put in U.S. Government interest pls ?

1000*98% = 980 ?
