FHSA and unqualified withdrawal

I have contributed to my fhsa for 2 years for a total of about $16,000 so far (made no contributions so far this year). If I make an unqualified withdrawal via rrsp does this mean I won't be able to contribute say, next year? I have not contributed up to 40K. Also, if I am able to contribute next year, will it not be tax-deductible? This is where I'm confused. I have only used about half the room, so I understand that I can't get that room back, but what about the remainder? Thx
