more than 20 1099-INT

Hi,

If I have more than 20 1099-INT (all are bank interest or new account bonus) I am learning today that IRS doesn't allow e-file!  Is this true?

Would IRS reject if I e-file by combining some of the 1099-INT amounts to stay under the limit of 20?

For example,  my spouse and I both have a 1099 from Bank A and Bank B

As I am doing joint filing, can I combine me + spouse the 1099-INT totals for Bank A ?

Or should I combine 1099 INT of  Bank A (mine) + Bank B (mine) ? 

 

Many thanks!
