Help with Suspended Passive Losses on a Rental that had been converted to primary

Hello,

 

If Rental A had been converted into Primary residence last year.  How can I carry forward the Suspended losses from Rental A to the following year so the losses can be used to offset income from Rental B?  If I remove Rental A from Schedule E, the suspended losses for Rental A is gone from Form 8582 in TT. 

Please advise, Thank you!
