I have not studied this in detail, so take it with a grain of your favorite seasoning.
I have never read of any Viking DNA in the Americas--ignoring, if they exist, the burials of Vikings who happened to die in Nova Scotia, meaning that modern Native Americans show no genetic trace of interbreeding. That doesn't mean it didn't happen: Nova Scotia was barren and sparsely populated, so it is possible that there were sexual liaisons that produced progeny who subsequently died out. Absence of evidence, after all, does not equal evidence of absence.
Curiously, there was a study done a decade or so ago that found in Icelanders a smattering of mDNA that is very similar to Native American mDNA. What that could mean is that the Vikings took one or more women with them back to Iceland. But that is not necessarily the right answer since the subclade of the C1 haplogroup that was found in Iceland is not an exact match--just very close--to the four American subclades. So it could be that some other group, perhaps Inuits further north and perhaps in Eurasia, contributed the mDNA to Iceland.
In summary, there is no evidence (that I am aware of) of Viking DNA in modern Native Americans except for that which entered the continent after 1492. There is suggestive evidence of the opposite happening--Native American mDNA introduced into Iceland--but the case has not been proved.
