Deductions & credits

Agreed ... code 5 is absolutely wrong ... it should be either a code 1 (if you got the check and made the deposit to the other HSA yourself)   OR  no form should have been issued for a direct trustee to trustee rollover.  

In the program, simply use code 1 so you can file the return while they issue you a corrected form ... this is the screen you should see to indicate the rollover ...
