What Records do I need to keep to show taxes are paid on interest on EE bonds?

[LCPow]

My sisters and I inherited some EE bonds from our Mom.  The bonds were not redeemed, they have been transferred to our names.

I understand that I can claim the interest earned up until the time they were transferred on Mom's 1040.

However, Treasury Direct will not keep track of the claimed interest and will not issue a 1099-INT until the bonds are redeemed.

Does anyone have a suggestion on a good way to keep track of the interest that Mom paid taxes on when the remainder will need to be paid when the bond is redeemed?

The information contained in the following link will instruct you how to report the interest.

With respect to record keeping, retaining copies of your mother's income tax returns showing the interest that was reported would clearly be optimal.
