Yes, they are not eligible for HOH unless they have a qualifying child live with them for 183 nights or more during the year.
I'm actually dealing with this as well for several clients and have struggled to get a clear answer on how to do the input.
What are you putting for your input? I've had to override in drake that they are eligible for the CTC because if you mark them less than 6 months then it doesn't give them the child tax credit. I know that you have to attached the 8332 to the efile and send a paper copy of the 8453 along with the 8332. Haven't found any consensus on the actual input though...
