In other words, no one knows the cleanliness or sanitary condition of your bottles. Time will tell. If you are concerned, sanitize some new bottles and fill them.
I had given away a few of my summer wheat beer and an IPA in bottles that I bottled from my taps. After 4wks they still held and had great carbonation. Don’t ask me why they took so long to drink them, but I was surprised myself at how well they stayed carbed.
Where do you expect the carbonation to go? Usually the issue with bottling from taps is that you lose some of the carbonation when bottling since the beer degasses a bit, but once you cap it, the carbonation should stay.
