How to correct p-values of two multiple regression models

This may be a really basic question, but I haven't found any helpful answers. Or I simply don't understand.

When correcting p-values of linear regression models, which p-values are corrected?

My problem:

I ran two multiple linear regression models with each 3 predictors and one dependent variable. Now I would want to run a FDR (Benjamini-Hochberg) correction. But I am not sure which p-values to correct and how.

1) I thought about correcting the p-values of all 6 coefficients of both models (t-statistics). I would sort them in ascending order, following this approach.

Would this be the correct way for adjusting the p-values? And what about the p- values of the F-Statistic of both models?

Thank you in advance.

Hence, only perform and correct for tests that are directly relevant to your research question. A summary of a linear model may automatically generate a $$p$$-value for the intercept, but if this test is meaningless (as it usually is), correcting for it would be wasteful in terms of power, if it weren't significant. If it is significant and you use e.g. the Benjamini Hochberg procedure, you could even inflate your false positive rate by including a nonsense result.
To conclude, first determine which $$p$$-values are actually of interest, then correct for those.
