The reality is a lot more complicated, but Erdogan would very much like you to simplify "organized Kurds = Terrorists"...
On the other hand, if the PKK is able to fundraise in Sweden and Finland like the IRA used to be able to in the US, then it seems logical for Turkey to use whatever leverage they have to decrease that activity, similar to GB.

You probably it is not the same, but for many, many people it is.
Also, your example missed the point where the Good friday agreement was drafted with US backing and help. This actually did more for the peace than decreasing fundraisers. Maybe Turkey should learn from this example?
I’m ask out of moderate ignorance in that I read the claims of Turkey and that of Sweden and Finland without a mechanism for deducing truth beyond various actors’ assertions.
While it would be optimal if Turkey did wage “Good Friday” peace to the extent that it is possible, it doesn’t seem likely since their position in the triad is that of GB, not the US. The non-NATO Nordics are more similar to the role of the US.
I don't have a solution either. I'll let professional negotiators find one :)
Also the Kurds are forming a state in parts of Syria and Iraq, where the "original" state is not able to restore order, especially against islamic militants. On top of that, the Turkish security forces have a long history of prosecuting Kurdish civilians. This makes the whole label of "terrorism" extremely murky and what Erdogan wants of NATO is much less nice than support against terrorists: He wants support and acquiescence in his war against Kurdish forces, including outside Turkey.
As a total outsider I see the situation as somewhat related to the Palestinian struggle: The more you are struggling for basic survival in the face of aggression, oppression and poverty, the less energy and motivation there is to curb the excesses of extremists in the own ranks.

"The problem is that these two countries are openly supporting and engaging with PKK and YPG. These are terrorist organisations that have been attacking our troops every day," Mevlut Cavusoglu said as he arrived in Berlin for a meeting with his NATO counterparts.
"Therefore it is unacceptable and outrageous that our friends and allies are supporting this terrorist organisation," he said. "These are the issues that we need to talk about with our NATO allies as well as these countries" Sweden and Finland, he added.
