i like merlot wine

Even if it's done fermenting, it's still loaded with CO2 and shouldn't be bottled yet. You need to either let it bulk age for several months or remove the gas via manual agitation or stirring. I strongly recommend the former over the latter. Bulk aging will not only allow the CO2 to escape on its own, but will also ensure that fermentation is 100% complete and allow the flavors to more fully develop and integrate.

You should never put a hydrometer directly into a carboy. If it breaks in the carboy, the whole batch could be lost. It may also drop too far into the carboy to be retrieved. You need to test the wine in a hydrometer test jar or other suitable beaker or vial.
