Do i need to send in 1099-R for $0.46

[SweetieJean]

No.  The IRS rounds amounts  less than 50 cents down to zero.

It is really your choice.

It does no harm to report it as received. It will be rounded to $0 and will then match what the IRS received.

However, this may cause a check this entry error since it is -0-. In that case, you could return to the 1099-R Summary and select the trash can icon next to the 1099-R entry to delete it.
